abstract = {Topologically ordered phases of matter can host fractionalized excitations known as {\textquotedblleft}anyons,{\textquotedblright} which obey neither Bose nor Fermi statistics. Despite forming the basis for topological quantum computation, experimental access to these exotic phases has been very limited. We present a new route toward realizing fractionalized topological phases by literally building on unfractionalized phases, which are much more easily realized experimentally. Our approach involves a Kondo lattice model in which a gapped electronic system of noninteracting fermions is coupled to local moments via the exchange interaction. Using general entanglement-based arguments and explicit lattice models, we show that gapped spin liquids can be induced in the spin system, and we demonstrate the power of this {\textquotedblleft}topological bootstrap{\textquotedblright} by realizing chiral and Z2 spin liquids. This technique enables the realization of many long sought-after fractionalized phases of matter.},
